A series of sculptures, paintings and illustrations that depict the fearlessness by the NYPD during the 9/11 attacks is part of a new public art exhibit at John Jay College.

Police Commissioner James O’Neill said the works were moved from Police Headquarters and the lobby of the Russell Office Building of the United States Senate for the four-month exhibit, which opened Friday.

“These paintings and illustrations have already served a critical role in upholding the legacies of our 9/11 heroes,” O’Neill said of the 23 works by nine artists.

“Nine-eleven is not [yet in some] textbooks. This exhibit brings the stories of our heroes to life in vivid illustrations so future generations can learn about the sacrifices of that day,” O’Neill said at the ribbon-cutting ceremony.

“We thank John Jay President Karol Mason, faculty and students for inviting this exhibit into their home. We also thank the families of those depicted in these illustrations and the first responders who participated in this project to share the stories of their loved ones or themselves so others never forget.

“For the next four months, this exhibition will show a new generation of New Yorkers what we faced, what we’ve overcome, and where we are today.”

The exhibit is titled “Bravery & Sacrifice” and is on display in John Jay’s Memorial Hall until December.
